Ujvall
You solved it yourself.
Millions of children sit in school
but do not learn the basics.
7 in 10
ten-year-olds in low- and middle-income countries cannot read and understand a simple text.
World Bank, UNESCO and UNICEF call this learning poverty.
45.8%
of rural Class 8 students in India can do a simple division sum. Fewer than half.
ASER 2024
2.2 billion
people are still offline, most of them in low- and middle-income countries.
ITU, 2025
Most AI tutors need fast internet and a new device.
The children who need help most have neither.
Ujvall runs on an ordinary computer, with no internet, and helps a child think, not copy.
Runs on basic computers
A refurbished computer with 8 GB of memory is enough. No graphics card.
Guides, never tells
It gives a hint or a question first. The child always does the last step.
How a session works
-
1
LC-0417
The child signs in with a learner code. Never a name.
-
2
40 min
The child practises maths for 40 minutes at a centre computer.
-
3
I tried 19 ÷ 3…
When stuck, the child opens Ujvall and types what they tried.
-
4
A named adult supervisor is always in the room.
How we keep it safe
Our rules, before any child uses Ujvall.
- Permission from the centre, consent from parents, and agreement from the child.
- No names or personal details. Learner codes only. Data stays on the computer.
- The tutor must answer about 90% of 50 test questions the right way, by guiding, not by handing out answers, before children see it.
- If it makes too many mistakes, we pause it and fix it.
- Results are reported for groups, never for one child.
Where we are
- Now
Working with 20 children at a children's home in Bengaluru.
- Next
A children's programme of over 200 children.
- Then
Principals and organisations across Bengaluru.

What lasts is a method others can repeat: the safety rules, the tutor instructions, the quality check and the cost sheet.
Another centre changes only the language, the syllabus and the prices.
